Introduction
Fluke Biomedical’s High Sensitivity 10 cc CT Chamber consists of a pencil-type
ionization chamber with sensitive length of 10 cm for computed tomography (CT)
Quality Assurance. This high sensitivity 10cc CT chamber has three times the sensitivity
of a standard 3.2 cc CT chamber and is designed to be used with your existing CT
phantoms. This new architecture provides more stable, reproducible dose measurements
for CT slices from 1 mm to 1 cm in thickness.
